Jackson thinks there is so much more material to explore, and hinted that the potential extra movie could be based on J.R.R. Tolkien's 125 pages of additional notes found at the end of third "Lord of the Rings" book The Return Of The King.
''I'd like to shoot a bunch more material that we could not shoot. There's so much good stuff in the index that we have not been able to squeeze into these movies,'' he said.
The first film, The Hobbit: An Unexpected Journey, is scheduled for release Dec 14.
